Description

[0001] This application is a divisional application of the patent "A special ice storage and ice transport ship" with application number 202323555256.2 and application date 2023-12-26. Technical Field

[0002] The utility model relates to the technical field of special transport ship equipment, in particular to a special ice storage and ice transporting device of a special ice storage and ice transporting ship. Background Art

[0003] LNG is the abbreviation of liquefied natural gas. Liquefied natural gas is a liquid that is compressed and cooled to its freezing point (-161.5℃). Its main component is methane. After combustion, it causes very little air pollution and releases a lot of heat. Therefore, liquefied natural gas is also recognized as the cleanest fossil energy on the earth. During the use of liquefied natural gas (LNG), a large amount of cold energy is released when it is converted from liquid to gas, and a separate gasification station or gasification device is usually required. Therefore, traditional LNG gasifiers usually use seawater or river water for gasification, which will discharge a large amount of cold energy into the environment, affecting the ecological safety and diversity of the water environment. At the same time, it also causes a waste of cold energy, which does not meet the current energy-saving and low-carbon environmental protection requirements.

[0004] In order to recycle LNG cold energy, the applicant has designed an LNG cold energy recycling device and applied for patent 2023234686269. This patent can better realize the recovery of LNG cold energy for ice making and achieve the purpose of recovering excess cold. Since LNG vaporizers are usually built at river and sea docks or shore locations, it is also necessary to consider designing a ship dedicated to ice storage and transportation, so as to facilitate the transportation of the recovered LNG cold energy to the required place by water transportation.
